Single crystals of KTiOAsO4, a material which is isostructural with the well-known nonlinear optical material KTiOPO4 (KTP), were grown by a flux process and its optical and dielectric properties characterized. Compared to KTP, KTiOAsO4 has a higher figure of merit for second-harmonic generation, larger electro-optic coefficients, and lower ionic conductivity. As a result, KTiOAsO4 should become a viable alternative for KTP.

    Birefringence plays a great role in phase matching of the nonlinear optical (NLO) crystals. Small birefringence restricts various crystals from achieving deep-ultraviolet laser output although they exhibit short UV cutoff edges and high second-harmonic generation (SHG) intensities. An access to...
